Ok well I actually know a lot about this stuff so here goes. YOu will never get $1 per click unless you heavily invested in adpacks with revshare programs. I would only trust paidverts and ptcshare. Having said that I want to add that the ROI is terrible considering you have to click every single day. Breaking even can take anywhere between 1-3 years. (yes it is that bad) they constatly change rules to benefit themeselves. (sometimes they change peoples money into points)
I would NOT trust Paidverts and Ptcshare. Like you said yourself,their actiions are not previsible since the time when they did a rollback of user's balance to worthless points. It's clearly a ponzi that still didn't collapse because they always do something shady to prevent it from collapsing but it won't work forever. They disguise the fact that they rely on a ponzi scheme by calling it "advertisement packs" that include some traffic to your website which is shady by itself. Funny enough,the admin have an active account that get all people that doesn't signup under a referral link as his referrals by default so he takes his part of the pie as well.
Not to talk about how they rent you refferals that make little or no profits for you so they pocket that extra money. They disguise it as advertising packs also for legal reasons. You got something in return( the adpack)
That means it is not an investment just a purchase. I'm not sure exactly the details but I know its to get around some legal bs. I don't have an issue with people using loopholes but they exploit it for self gain and greed.
Plus it isn't even free you have to login every day and if you forget you get no referrals payment that day. Some people say clicking ads is not work but it feels very much like work after a few months.
